Non-authentic ASIX USB to LAN solution inside or not? If yes, please contact the manufacturer of your
USB to LAN device to get proper drivers instead. ASIX DOES NOT GUARANTEE AND PROVIDE ANY SUPPORT FOR

AX88796C -- Low-Power SPI or Non-PCI Ethernet Controller

The AX88796C is a SPI or non-PCI Ethernet controller with low power, low-pin-count and variable voltage I/O for the Embedded and Industrial Ethernet applications. The AX88796C supports 8/16-bit SRAM-like or Address-Data Multiplex interface with variable voltage I/O, providing a glue-less connection to common or high-end MCUs. The AX88796C also provides an alternative SPI slave interface for MCUs with SPI master for simplifying host interface connection. The AX88796C integrates on-chip Fast Ethernet MAC and PHY, which is IEEE 802.3/802.3u 10BASE-T/100BASE-TX compatible, and embedded SRAM for packet buffering to accommodate high bandwidth applications. The AX88796C offers a wide array of features including support for advanced power management, high performance data transfer on host interface, IPv4/IPv6 checksum offload engine, Auto-MDIX, and IEEE 802.3x and back-pressure flow control. The AX88796C supports two operating temperature ranges, namely, commercial grade from 0 to 70 °C and industrial grade from -40 to 85 °C. The small form factor of 64-pin LQFP package helps reduce the overall PCB space. The programming of AX88796C is simple, so the users can easily port the software drivers to many embedded systems very quickly.

Supports full duplex operation with IEEE 802.3x flow control and half duplex operation with back-pressure flow control

Supports auto-polling function

Supports 10/100Mbps N-way Auto-negotiation operation

Advanced Power Management features

Supports dynamic power management to reduce power dissipation during idle or light traffic period

Supports very low power Wake-On-LAN (WOL) mode when the system enters sleep mode and waits for network event to awake it up. The wakeup events supported are network link state change, receipt of a Magic Packet or a pre-programmed Microsoft Wakeup Frame or through GPIO pin
